PATENT OFFICE JAMES KANTOR, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE LIQUIDCARBONIC COR- PORATION, OF QHICAGO, ILLINOIS FILLING MECHANISMApplication filed. March 14, 1927. Serial No. 175,316.

My invention relates to improvements in,

filling mechanisms of the type which are adapted to dispose measuredamounts of liquid, such as syrup, in bottles, and it consists in thecombinations, constructions, and arrangements herein described andclaimed.

An object of my invention is to providc'a filling mechanism inWlllClltllG capacity of the measuring means may be varied to theslightest fraction of an ounce.

A further object of my invention is to provi-de a device of the typedescribed by means of which desired quantities of the liquid may bedisposed in each bottle, irrespective of the temperature effect upon theliquid or the den sity of the liquid used.

A further object of my invention is to provide a device of the typedescribed which may be readily substituted for the old type of measuringmeans.

A further object of my invention is to provide a devlice'of the typedescribed which is simple in construction, durable and eflicient forthe-purpose intended. I

Other objects and advantages will appear V in the followingspecification, and the novel features of the invention will beparticularly pointed out in the appended claims. r

My invention is illustrated in-the accompanyingdrawings, forming part ofthis application, in which :Figure- 1 is a side elevation of my device,portions thereof being shown in section,

Figure 2 isa plan view of myvdevice, and

Figure 3is a sectional View of a portion of my device.

In carry ng out my mvention, I provide a liquid tank '1 having one ormore openings 2 in the bottom wall 3 thereof. Aguide or supporting rod 4is slidably disposed in a bushing 5 which extends through the bottom 8of the tank 1. A bell 6 for receiving the neck of a bottle, which isindicated at 7,-is

rigidly mounted upon the lower end of the guide rod 4- A compressionspring 8 is disposed concentric with the guide rod 4 and bears at oneend .upon the bell 6 and at the other end upon the bushing 5. A support9 in the form of a triangular block is secured to the upper end of theguide rod 4 by means of a nut 10. A measuring cup which is composed of acylindrical body portion 11 and a bottom portion 12 having its innerwall tapering downwardly toward the center thereof is disposed in thetank 1 in alignment with the opening 2.. The measuring cup is soconstructed that the cylindrical body portion 11 may be moved withrespect to the bottom por tion 12 and still prevent a liquid frompassing from the cup between the body portion 11 and the bottom portion12. The bottom portion 12 is provided with a groove 13 for receiving oneend of a fork 14. The other end of the fork 14: is rigidly secured to asupporting rod 15 which extends upwardly through the support 9 and isrigidly secured thereto by a nut 16. In this manner, the bottom portion12 is rigidly held against movement with respect to the support 9. I

A sleeve 17, rigidly secured at 18 to the body portion 11, is disposedconcentric with is providedwith indicating lines 25 circumferentiallydisposed thereupon. A look nut '26ris disposed upon the reduced portion23 for'holding the indicating cylinder 24% in any adjusted position.

a The collar 22 is -held against longitudinal displacement by a forkedretaining plate 27,

the forked 'end28 of which is receivable in an annular groove 29 ofthecollar. "The forked retainingplate 27 is rigidly held bev tween thesupport 9 and the nut 10. I An indicating line or groove 30 is disposedin the forked retainingmember 27, see Figure 2. An indicating wheel-31is disposed concentric with the collar 22 and is, provided withindicating lines 32 which are equally spaced thereupon and extendinwardly from the peripheral edge thereof, An adjusting nut 33 isprovided with an internally threaded portion 3 1 which is adapted toreceive external threads 35 upon the collar 22. A set. screw 36 extendsthrough the adjusting nut 33 and is in engagement with the indicatingwheel 31. The set screw 36 acts as akey to prevent rotation of thenut33, and locks the indicating wheel 31 against rotation with respect tothe adjusting nut 33.

A liquid valve tube 37 is rigidly secured to the tank 1 and extendsupwardly through the opening 2 in the bottom 3 to a point above thelevel of a liquid 38. This liquid is kept at the predetermined level bymeans not shown. The lower portion of the liquid valve tube 37 extendsdownwardly through the hell 6 and is adapted to enter the bottle 7. Adrip check 39 is adjustably secured to the support 9 by the nut 16 andis positioned in alignment with the liquid valve tube 37.

The check 39 may be moved into and out of alignment with the tube 37 fora purpose hereinafter described.

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood. As stated heretofore theliquid 38 maintains approximately the level shown in Figure 1,irrespective of the speed at which the liquid passes from the tank.

Let us assume that the operator wishes to place four ounces of theliquid 38 into the bottle 7. The measuring cup, as shown in Figures 1and 2, is set to receive just four ounces of the liquid. As the bottle 7is moved up .wardly by means not shown the bottle engages with the hell6, thus raising the bell, the guide rod 4, the support 9, and themeasuring cup upwardly to a point where the up measuring cup; When themeasuring cup has reached its uppermost position, the drip check 39 willhave been raised from the liquid valve tube 37 and the upper extremityof the liquid valve tube will be adjacent the lower portion of thetapering surface of the bottom portion 12. This allows the liquid whichhas been retained in the measuring cup to flow downwardly through thetube 37 into the bottle 7. The tapering surface of the bottom This timeremains the same, irrespective of the surrounding temperature and thespecific gravity of the syrup. As for instance, a liquid, such as syrup,Wlll flow at a slower rate of speed during a relatively low surroundingtemperature than when the surrounding temperature is relatively high.Some syrups or liquids, owing to their density, require more time toflow from the measuring cup into the bottle than do others. To allow forthe slowness of the flow of the liquid during a relatively lowtemperature, or with the use of a relatively heavy syrup, the bodyportion 11 may be moved upwardly with respect to the bottom portion 12by rotating the adjusting nut 33 in a clockwise direction, looking fromthe top of the ad justing nut. With this adjustment, the measuring cupmay be tested to allow the desired four ounces of liquid to pass intothebottle in the limited time. After this ad justment has been made, byremoving the set screw 36, the indicating wheel 31 may be reset toregister correctly. By again inserts ing the set screw in place, theindicating wheel 31 may be held in adjusted position. In resetting theindicating wheel, it is obvi ous that the indicating line adjacent themarking O should be in alignment with theindicating line or groove 30.

As the bottle 7 moves downwardly, the measuring cup is also moveddownwardly by" the force of the compression spring 8, and" the dripcheck 39 engages with the upper end of the liquid valve tube37 forpreventing any'liquid which should remain in the tube from passingtherefrom until another bottle is brought into alignment withthe tube.The drip check 39 is essential when the device is used in a lowsurrounding temperature or with a heavy liquid for holdingall the liquidover four ounces which is received in the measuring cup. If the check 39is moved out. of alignment with the tube 37,the liquid in the tube wouldcontinue to flowtherefrom;

Let .usassume that the operator wishes to place three ounces of liquidwithin the bottle. By rotating. the adjusting nut 33. in acounter-clockwise direction, looking from" the top of the nut, thesleeve 17 vis moved downwardly upon the supporting --rod 15 thusmovingthe body portion 11 downwardly with respect to the bottom portion12 and decreasing the capacity of the measuring cup to three ounces. Thepurpose ofthe gradu ations 25 upon the cylinderQt is to indicate to theoperator that when the line adjacent the marking ,3 oz. has been moveddownward- 1y into alignment with the upper extremityl of the collar 22and theindicating line adj acent the marking() upon the indicating wheelhas been brought into alignment with the indieating line 30, themeasuring cup will hold i just three ounces of the liquid38. Theindicating lines upon the wheel 31 each represent g of an ounce.One-half a revolution of the indicating wheel 31 and adjusting nut 33 7increases or decreases the capacity of the measuring cup of an ounce,and one whole revolution of the indicating wheel and adjusting nutincreases or decreases the capacity of the measuring cup of an ounce. Inthis manner, the body portion 11 may be moved with respect to the bottomportion 12 so that the measuring cup will receive any desired amount ofthe liquid 38. It is obvious that with this adjusting means the capacityof the measuring cup may be varied at will from a fraction of an ounceand more. After the body portion 11 has been moved to the desiredposition with respect to the bottom portion 12, the indicating wheel 31may be locked against rotationby a screw which is carried by the support9.
